The addition of magnesium alloy elements followed by a flame-hardening process will change the phase configuration in gray cast iron. This study aims to investigate changes microstructure and hardness due these two processes. is conducted adding FeSiMg as carrier for magnesium. Metallographic examination observe was carried out using Scanning Electron Microscope (SEM) Energy-Dispersive X-ray Sp...

In this present work effect of temperature and graphite contents on the microstructural and mechanical properties of iron based powder metallurgy freeform was studied. The different graphite contents (0%, 2%, 5% and 10%) were mixed in iron powder and compact them in 100 KN. These specimens were sintered at 7000 C, 8500 C and 10000 C in muffle furnaces. Microstructural properties were evaluated ...

The cylinder liner is one of the important parts a diesel engine. Gray cast iron main material for manufacturing liners due to its good casting performance, convenient processing wear resistance and low cost. In present work, effects vanadium (V) tin (Sn) on microstructure properties gray were studied. Results show that increasing contents V Sn can not only refine graphite, but also reduce pear...

Abstract This paper describes and validates a methodology for implementation of full-scale sand-casting simulation in general-purpose finite element software, including mold filling, heat transport, solidification kinetics, chemical microsegregation prediction microstructure material properties. The model, customized gray cast iron, includes novel methods handling interaction between parallel d...

Abstract In the work, from standpoint of a systematic approach, methodology for technological design repair and restoration worn parts using methods to improve quality working layer is proposed. For stages product life cycle, solving problem extending service after parts, general scheme structure information support were developed that ensure layer. A variant process cylinder liners modified gr...
